数に制限が加わるという点で欠点がある。Optical relay lens systems of this type are well known. FIG. 1 shows a simple example. In FIG. 1, all image aberrations are corrected. However, this optical relay lens system has a very significant vignetting that makes it almost useless for film and television. Another known optical relay lens system shown in FIG. 2 eliminates vignetting but does not correct the image field. Aberration increases with the number of optical relay lens systems attached to the optical device.
This problem has been solved in the art by correcting the objective lens and / or the eyepiece lens. However, in such an optical relay lens system, different objective lenses or eyepieces must be used every time, and the number of optical relay lens systems is changed to change the total length or the image orientation. . It should be noted that uncorrected separations require precise tolerances, and the ability to correct such objectives has the drawback of limiting the number of optical relay lens systems.

An optical relay lens system according to the respective patent specifications is known. According to these specifications, the image force field is
Corrected to eliminate vignetting. However, a disadvantage of these systems is that they have a large focal length, difficult to align and therefore expensive unbonded lenses. These systems also require extremely precise mounting.
